由于勘探孔距存在一定距离,相邻勘探孔之间的地层分布有时会有很大变化。本文简单阐述了在勘察过程中对于地层分布变化比较大的情况下,为能更准确的描述地层特性而采取补孔实施方案。补孔既要能查明工程场地内地层分布情况,又要考虑经济成本。如何合理的布置勘探孔,采用准确的补孔方案,是本文需要探讨的问题。 Due to the existence of a certain distance between the exploration hole, the formation distribution between adjacent exploration holes sometimes changes greatly. This paper briefly describes the implementation of backfill in order to describe the stratigraphic characteristics more accurately when the distribution of ground strata varies greatly during the survey. Fill hole should be able to identify the distribution of the formation within the project site, but also consider the economic costs. How to arrange the exploration holes reasonably and adopt the exact scheme of the hole repairing is the problem to be discussed in this article.
